STOPPER FOR BOTTLES.

. (N model.)

To all whom it may concern.-

Be it known that I, MZRTEN ELFSTRAND, a

' subject of the King of Norway and Sweden,

and a resident of Upsala, Sweden, have invented new and useful Improvements in Stoppers for Bottles and the Like, of which the follow ing is a specification, reference being had to the drawing accompanying and forming a part hereof.

This invention relates to improvements in stoppers for bottles and the like through which the liquid may be poured out Without removing the stopper.

The object of the invention is to provide a stopper of a simple construction which mail be used also for bottles or the like containing volatile fluids, such as ether or the like, without any loss of the contents of the bottle when the stopper is closed and in which wearing will have no perceptible influence on the capacity of the stopper to close a bottle or the like gas-tight.

The invention consists, briefly, in providing on the upper side of a stopper of cork or other elastic material, such as india-rubber, a turnable plate having two or more holes or openings corresponding to channels or pipes in the stopper and in providing means for pressing the said turnable plate air-tightly against the stopper.

The invention also consists in the combina tions and arrangements hereinafter describe and claimed.

In the accompanyingdrawings I have shown a constructional form of my invention.

Figure 1 shows a vertical section of a dropbottle provided with a stopper constructed in accordance with the present invention, and Fig. 2 shows a detail.

Referring to the drawings, a plug or stopper proper, Z), of elastic material, such as cork, is inserted in a bottle a. In the said stopper are in well-known manner fixed two pipes (Z and e, of glass, metal, or other suitable material, of which the one 0 is adapted to let in the air into the bottle. On the upper side of said stopper 6 is provided a plate f or other suitable body of glass, metal, or any other material. The said plate or body is turnable on a. screw y, fixed in the said stopper 7), a nut it being provided on said screw for press ing the plate f air-tightly against the upper side of the stopper 6 by compressing the stopper in longitudinal direction. Instead of the said nut it any other device-for instance, a spiral spring, a small plate held by a pin, or the like-may be used for pressing the said plate f against the stopper Z); provided with two holes and is, arranged in such manner in relation to the said pipes (Z and e that the latter in a certain position of the plate f will communicate with the atmosphere by means of the said holes vi and 1:. In the one I; of the latter is inserted a droppipe Z.

It is obvious that a stopper of the kind described, provided the plug Z) be made of sulliciently-elastic material and from the outset sufficiently compressed, will always be able to close the bottle air-tightly, inasmuch as the wearing of the surfaces bearing against each other will be compensated by the elasticity of the plug 6.

Though the stopper illustrated in the drawings is provided with a drop-pipe having a tongue-shaped extension, it is obvious that the said drop-pipe may be dispensed with--for instance, in the case that the liquid in the bottle is to be poured out in the usualmanner through the stopper or the bottle is to be used for inhaling purposes or the like.

N 0 claim is herein made to the tongue shaped extension of the droppipc, since the same is claimed in an application tiled by me .July 10, 1902, of which this application is a of, a stopper of elastic material, two channels in the said stopper, a turnable body on the latter provided with two holes corresponding to the said channels, a shaft for the said body fixed in the said stopper, means for pressing The platef is the said turnable body against the said stopto this specification in the presence of two subper and simultaneously compressing the said scribing Witnesses. stopper, a drop-pipe in the one of the said holes, and an air-pipe in the one of the said 5 channels, substantially as and for the purpose Witnesses:
